Really nice design
So this was a really nice "DESIGN" and good progression of the work you have here, I love the black and white drawing most because its the "RAW" drawing the other colored ones are pretty good too, I think all this needs is some backround props to accent the main focus here, but anyways really nice work here and love this little robot you here would love to see much more designs like this.
